Teledyne Hanson’s Analytical Research Center (ARC) provides analytical lab services in support of pharmaceutical, nutraceutical, and cosmeceutical research and development, manufacturing, quality control, and regulatory compliance. The ARC, located in Chestnut Ridge, New York, leverages Hanson’s decades of experience and innovation in the fields of dissolution, diffusion, and disintegration testing. Hanson Research, founded in 1951, is the innovator of the Model A cell shown in USP <1724> and the joint developer, along with the U.S. FDA and USP, of modern-day six-vessel dissolution testing instruments.

In additional to testing and certification of ingredients and products, our chemists are able to quickly develop, validate, and transfer a broad range of analytical methods for time-sensitive projects to help ensure your products are rapidly approved for release into the market. Our NY facility also acts as a Demonstration and Training Center (DTC) for Teledyne Hanson analytical testing instruments.
